Single loop surgical fastener apparatus for applying variable compression

摘要

A surgical fastener applying apparatus (1000) comprising a first jaw (1010) containing a first row of first surgical fasteners and a second row of second surgical fasteners and a second jaw (1008) containing a first row (1206A) of first anvil pockets (1204) and a second row (1206B) of second anvil pockets (1204) deforming the respective first and second rows of fasteners. At least one of the first fasteners has a first unformed length and a first formed length forming a single loop configuration to form a first compressive space when deformed by the anvil pocket. At least one of the second fasteners has a second unformed length and a second formed length forming a single loop configuration having a second compressive space. The first unformed length and first formed length of the at least one first fastener is less than the second unformed length and second formed length of the at least one second fastener.
